Windows 8 Release Preview: Key Features

Microsoft made the Windows 8 Release Preview version available Thursday, marking one of the final steps before the new version of the operating system hits the streets and computers around the world. Windows 8 includes a host of new features and capabilities, and represents a big bet by Microsoft that it can keep desktop PCs a centerpiece of business and consumer computing in the age of smartphones and tablets. We'll show you some of the key features Microsoft is counting on to accomplish that in this slideshow.

For businesses, Windows 8 is designed to maintain corporate security and manageability as more workers bring in their own consumer-style gadgets. "Windows 8 will deliver no compromise experiences on a range of devices from tablets and PCs to desktops," Microsoft chief operating officer Kevin Turner said earlier this year. "It will give people functionality they love and the enterprise-grade capabilities that IT departments demand."

Windows 8 will be available in two versions when it launches later this year. One version will run on x86 PCs, laptops, and slates or tablets powered by Intel or AMD chips, and will offer users the choice of working in the familiar Windows Explorer desktop or in the new, touch-centric Metro mode. The other version will run on tablets that run Qualcomm, Texas Instruments, or Nvidia chips based on the ARM reference design, and will only offer the Metro interface.

Turner said Microsoft expects businesses to find a home for both types of devices as workers demand mobility while on the road and full productivity while in the office. "Should I have touch or a mouse and a keyboard? Depending on the job function, the answer is yes and yes," said Turner. "Should I have security or should I let people bring their own technology to work? In the past the answer would be no, but now it is yes and yes."

IDC analyst Al Gillen said Windows 8, with its ability to stretch across desktop and tablet form factors while maintaining compatibility with existing corporate security and management infrastructures, could help Microsoft limit the extent to which non-Windows devices eat into its share of the enterprise OS market. "We believe Windows 8 will bring an evolutionary solution to Windows users that delivers business productivity, while helping IT to manage and secure new devices," said Gillen.

The next expected milestone for Windows 8 will be the release to manufacturing (RTM) date, which is targeted for the end of July, according to a blog post by Microsoft's Windows chief, Steven Sinofsky.

Between now and RTM, Microsoft will continue to refine the code, looking at issues including setup matters, compatibility glitches, and performance. It will also make some last tweaks to the touch-friendly Metro interface and feature set.

As predicted, Microsoft says Windows 8 and Windows RT will arrive for the crucial holiday retail season. The exact date for when the first Windows 8 machines will ship, Sinofsky notes, will be up to the hardware partners.
